ok but what harness do i purchase? do i find one based on the car or the head unit I'm installing? stupid question i know, but im trying to learn a lot at once haha.
also do i need seperate amps to power my sub (probably gonna get a 12" Q from fi) and speakers, or will one amp do the job? I understand that each amp can handle so much power, but im still a little unsure how to tell how much and how much my sub + speakers are outputting. Could someone clarify that for me real fast so I know? And what last thing is I see the term ohms come up a lot. I have obviously gathered they are important but what exactly does it mean to be 1, 2, or 4 ohms and what is the relevance of that to how i have my amp/subs/speakers set up?
